Carice Van Houten stars on "Game of Thrones" as the red priestess Lady Melisandre. Her Twitter and Instagram feeds are fun and full of jokes.

After the premiere of season six, fans learned that Melisandre's necklace was actually keeping Melisandre looking young and beautiful despite her true form being a wizened old woman. Van Houten tweeted this out the next day:

Isaac Hempstead-Wright is the teen behind Bran Stark's enigmatic presence on the series. He's also behind some great "Game of Thrones" tweets.

Wright is another cast member who often tweets relevant comments or photos after an episode of "Game of Thrones" premieres. When the fifth episode, "The Door," revealed Bran was responsible for ruining Hodor's life, Wright tweeted:

Wright's on- and off-screen friend Kristian Nairn plays Hodor, and he was firing right back on Twitter after the devastating episode.

Lena Headey (Cersei Lannister) is another cast member fond of Twitter. She often interacts with fans there and posts photos.

Headey was hyping up fans before the sixth season kicked off:

Eugene Michael Simon plays the religious fanatic Lancel Lannister, but in real life he's more of a Twitter fanatic.

Simon also speaks directly to fans through his Twitter account, and always let's people know where he's headed and what new adventures he's taking.

Daniel Portman (Podrick Payne) is yet another "Game of Thrones" actor who loves to tweet about the series as it airs.

Anyone who the uses the hashtag #InPodWeTrust about their own character definitely deserves a follow in my book.

Last but not least, Gwendoline Christie (Brienne of Tarth) loves to retweet memes about her woman-warrior character on the show and get fans hyped for upcoming episodes.
